2015-07-28ARM: kill off set_irq_flags usageRob Herring
set_irq_flags is ARM specific with custom flags which have genirq equivalents. Convert drivers to use the genirq interfaces directly, so we can kill off set_irq_flags. The translation of flags is as follows: IRQF_VALID -> !IRQ_NOREQUEST IRQF_PROBE -> !IRQ_NOPROBE IRQF_NOAUTOEN -> IRQ_NOAUTOEN For IRQs managed by an irqdomain, the irqdomain core code handles clearing and setting IRQ_NOREQUEST already, so there is no need to do this in .map() functions and we can simply remove the set_irq_flags calls. Some users also modify IRQ_NOPROBE and this has been maintained although it is not clear that is really needed. There appears to be a great deal of blind copy and paste of this code.

2012-07-01ARM: fiq: change FIQ_START to a variableShawn Guo
The commit a2be01b (ARM: only include mach/irqs.h for !SPARSE_IRQ) makes mach/irqs.h only be included for !SPARSE_IRQ build. There are a nubmer of platforms have FIQ_START defined in mach/irqs.h for FIQ support. arch/arm/mach-rpc/include/mach/irqs.h:#define FIQ_START 64 arch/arm/mach-s3c24xx/include/mach/irqs.h:#define FIQ_START IRQ_EINT0 arch/arm/plat-mxc/include/mach/irqs.h:#define FIQ_START 0 If SPARSE_IRQ is enabled for any of these platforms, the following compile error will be seen. arch/arm/kernel/fiq.c: In function ‘enable_fiq’: arch/arm/kernel/fiq.c:127:19: error: ‘FIQ_START’ undeclared (first use in this function) arch/arm/kernel/fiq.c:127:19: note: each undeclared identifier is reported only once for each function it appears in arch/arm/kernel/fiq.c: In function ‘disable_fiq’: arch/arm/kernel/fiq.c:132:20: error: ‘FIQ_START’ undeclared (first use in this function) The patch changes fiq code to have init_FIQ take FIQ_START from platforms as a parameter and assign it to variable fiq_start which is to replace FIQ_START uses in enable_fiq/disable_fiq.

2012-02-21ARM: rpc: make default fiq handler run-time installedRob Herring
Only rpc uses disable_fiq macro. Change it to a run-time installed default FIQ handler. The handler is installed before FIQ is enabled so the behavior should be unchanged. Signed-off-by: Rob Herring <rob.herring@calxeda.com> Acked-by: Nicolas Pitre <nico@linaro.org>

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
